ring F, of felt, rubber, or other suitable flexithe same and the bars '1) of the balloon. This be beneath the trough, and will thus allow of the freest play possible to the back draft or current induced in these sections of the cloth through the trough II and flue J. In order to properly guide said flue, the pins 6 e are provided on the outer face of the ring E, between which its upper part is held in place. Though I have described only one fine, J, it must, however, be understood that each end of the trough His provided with one, both being attached in the same manner to the ends of the casing A, both ends of my machine being alike in every respect.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. 'In a dust-collector, the combination,with the revolving balloon B and the casing A, of the rings 0, D, E, and F, the cord (1, coilspring f, threaded bolt 9, bracket 71, and adjusting-nut c, substantially as shown and described, and for the purpose set forth.

2. In a dust-collector, in combination with the balloon B, casing A, and inverted trough II, having longitudinal bars IL 72/, the line J,

having pin j, the coil-spring k, threaded bolt.

Z, bracket m and nut 02, substantially as shown and described, and for the purpose set forth.

3. In a dust-collector the combination, with the balloon B, trough H, the flue J, fasteningpin j, spring, k, bolt Z, bracket m, and nut 11, of the guide-pins e 0, held in the casing A, substantially as shown and described, and for the purpose set forth.

at. In a dust-collector, the combination, with a revolving balloon, a case iuclosing the same, and. metallic rings fastened to each of said parts and interposed between their respective bearing-edges, of an annular band of felt or of any other flexible material interposed between said metallic rings, and having one of its rims fastened to the case, while its other rim is suitably held against a projection of the ring of the balloon, so as to form an air-tight joint between the bearing parts, substantially as set forth.

5. In a dust-collector, the combination, with a revolving balloon, a case inclosing the same, and metallic rings fastened to each of said parts and interposed between their respective bearing-edges, of an annular band of felt or of any other flexible material interposed between said metallic rings, and having one of its rims fastened to the case, and an elastic binder adapted to keep the other rim of the annular band in constant contact with the projecting periphery of the revolving balloon-ring, substantially as set forth.

6. In a dust-collector, the combination, with a revolving balloon, a case inclosing the same, and an inverted trough held in the open center of said balloon, of a flue hung over each end of said trough, and connected to the sides of the case by an elastic binder, by means of which an air-tight joint is secured between the edges of the trough and the balloon-bars, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Viscousin, inthc presence of two witnesses.

WILLIAM RICHARDSON.
